Describe the enhancement and the motivation for it.
I would like to be able to collapse individual diff chunks after reviewing. Some of our reviews are quite long, and I would like to be able to collapse chunks if they don't need further review. I would like this collapsed state to be maintained so that if I leave and return to the diff, my collapsed sections are still collapsed. Ideally, this would work like selecting a chunk of lines to reviews, and either selecting "collapse" or "don't need to see again", something like that. This would only be for a given reviewers private view, not something that is published to the reviewee.
What operating system are you using? What browser?
